    <p>I'm trying to implement upload code for grails. When the file is processed on my controller I get this error:</p> <pre><code>ERROR errors.GrailsExceptionResolver - Exception occurred when processing request: [POST] /com.jason.score/fileResource/uploads Stacktrace follows: groovy.lang.MissingMethodException: No signature of method: static org.hsqldb.types.Binary.storeMyFileMethod() is applicable for argument types: (org.springframework.web.multipart.commons.CommonsMultipartFile) values: [org.springframework.web.multipart.commons.CommonsMultipartFile@1a17db8] at com.jason.score.FileResourceController$_closure4_closure6.doCall(FileResourceController.groovy:73) at com.jason.score.FileResourceController$_closure4.doCall(FileResourceController.groovy:72) at com.jason.score.FileResourceController$_closure4.doCall(FileResourceController.groovy) at java.lang.Thread.run(Thread.java:662) </code></pre> <p>My controller function looks like this:</p> <pre><code> def uploads = { Collection result = [] Binary binary request.getFileNames().each { binary = Binary.storeMyFileMethod(request.getFile(it)) result &lt;&lt; [name: binary.getFileName(), size: binary.getFileSize()] } render result as JSON } </code></pre> <p>My view looks like this:</p> <pre><code> &lt;g:form name="fileupload" url="[action:'uploads',controller:'fileResource']" method="POST" enctype="multipart/form-data"&gt; .... &lt;input type="file" name="files[]" multiple&gt; &lt;/g:form&gt; </code></pre> <p>Can anyone explain what is going wrong and how I can process each file that is uploaded (can be multiple files)?</p>

    1. COWhat is `Binary`, and where did you find that you can call `storeMyFileMethod()`? The error says the method doesn't exist (for `org.hsqldb.types.Binary`), and the Internet seems to support that.

    2. COAlso, can you elaborate what you mean by "process each file"? "Process" could mean any number of things: storing it to disk, saving it into a database, etc.

    3. COThank you for your response. I am trying to use the jquery file upload plugin found here: http://grails.org/plugin/jquery-file-upload. I was just trying to get the example code to work. By process, I mean to upload the file, get its file size/name and parse it as a JSON response. Any help would be great.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
